    Printed Greg's scoops in Proto-Pasta matte HTPLA. Loving the surface of this matte PLA. Really has a non 3D printed feel. This is after annealing in the oven for 60 minutes at 110C then a 30 minute cool down to prevent warping. I left supports in and placed it on parchment paper on a baking pan. Settings: 0.15mm layers, 220/60C fan 20% 1-2 then 100% with wolfbite nano as the adhesive.

    gorgeous!, looks like polywood pla and the promise (never came thru) of multiple colors in that porous/foamy material. File Feb 14, 9 25 08 PM.jpeg

    You could mistake that for a gypsum print. Very cool.

    Great print there Henry. I wonder how much of the look comes from the 0.15 layers, and how much from the material itself. I'm curious if the look changed during annealing, and also what led you to decide to bake the print in the first place?

    I decided to bake it for extra thermal resistance (Greg said it needed a high TG). I also printed the scoop with the same settings in PLA/PHA so I'll post that pic tonight for comparison

    Where's the scoop going? Is this the think to cause the air from the heatsink fans to go up and away from the print area? If so, that doesn't seem like it would be a super hot area. Are these actually added in front of the fan and the fan turned around?

    This is for the heat break fan so that it is sucking air from above rather than hot air from the bed

    I've seen some of the matte PLA on PP's Instagram and it does look really nice!

    Here is the same part printed in regular MeltInk PLA/PHA, which still looks very very nice, but just not quite as awesome (same settings):

    @Spoon Unit the shroud/scoop is from Greg and here is the post:

    Decided to print in PLA, 0.3 layer, no supports.

    HTPLA looks nice but apparently not so good?

    Mechanical strength in this application is of course irrelevant (if you have high mechanical load on your heat brake fan scoop if you are having way, way, way bigger problems) I only wanted some heat resistance. Sounds like regular PLA might have worked as well.

    You'd be a bit disappointed if you spent the money on carbon fibre thinking it would provide extra strength.

    I thought it mostly claimed to be super stiff which can be useful if that's what you need. But super stiff things are often not resilient since they don't flex...

    Indeed. I can only refer to Colorfabb who have the decency to produce comparable data sheets.

    Their PLA is stiffer than their other basic materials.

    Their Carbon Fibre XT (PETG + Carbon Fibre) is twice as stiff as PLA (from memory).

    Their HT filament (also a PETG) is the toughest (difficult to smash) as well as having the best temperature resistance.

    Their Carbon Fibre filament also wins for highest tensile strength.

    Regardless of all the requirements, that print of Henry's looks awesome. My PLA scoops do seem to be OK, and looking at how close they are, I'm actually a little surprised there's no obvious effect. Perhaps the socks are also helping keep some heat from drifting to the scoops.

    XT-CF20 is definitely stiffer and good in tensile mode but fails totally under high stress with no early warning. Much better than the same part in PLA.
